Microscopic Hematuria | Causes & Risk Factors

What are some common causes of microscopic hematuria?

Here are some common causes of blood in the urine:

• Kidney infections
• Enlarged prostate
• Urinary tract (bladder) infection
• Swelling in the filtering system of the kidneys (this is called "glomerulonephritis")
• A stone in your bladder or in a kidney
• A disease that runs in families, such as cystic kidney disease
• Some medicines
• A blood disease, like sickle cell anemia
• A tumor in your urinary tract (this may or may not be cancer)
• Exercise (when this is the cause, hematuria will usually go away in 24 hours)
